If any of that was in the last 50 years, it means nothing in terms of what you actually know. You’ve proven this on multiple occasions.
Two men considering a religious vocation were having a conversation. "What is similar about the Jesuit and Dominican Orders? " the one asked.
The second replied, "Well, they were both founded by Spaniards -- St. Dominic for the Dominicans, and St. Ignatius of Loyola for the Jesuits. They were also both founded to combat heresy -- the Dominicans to fight the Albigensians, and the Jesuits to fight the Protestants."
"What is different about the Jesuit and Dominican Orders?"
"Met any Albigensians lately?"
As a honest RC will tell you, that does not mean you know a whole lot about the Catholic faith (including the details of what the RCC means by "salvation by grace," with her means of dispensing it, and her formal means of justification, etc.) And this RC blame conversions on the subjects being "poorly catechized," which either means the church they want us to convert to is a very poor discipler or her subjects are of low IQ, or have little incentive to learn.
And while being ignorant of much of what Rome teaches, at least the details, yet what most RCs "get" is what Rome effectually conveys, which is that she is the one true church which has the "in" with God, and as long as one dies in her arms then eventual entrance into glory can basically be expected. The way Rome treats Ted Kennedy RCs in life and in death itself effectively teaches this.
I myself have learned far more since becoming born again than before, even though I also was an altar boy for years, and was "confirmed" as a weekly and every HDOO Mass-going RC, with 2 uncles were priests. And also as one I actually become born again at age 25 thru sincere deep repentance and trust in the Lord Jesus to save me by His mercy (which need I had never realized) - not any merit of mine - and realized the profound basic transformational changes of Biblical regeneration (thanks be to God). I has kind of like the penitent publican of Lk 18.
The Lord is nigh unto them that are of a broken heart; and saveth such as be of a contrite spirit. (Psalms 34:18)
And not really knowing other churches I remained as a weekly Mass-going (and confession) largely ignorant of Scripture RC for 6 years (evangelical radio helping to feed my hungry soul) with a heart to serve God, becoming a lector and CCD teacher. Meanwhile I evangelizing on my own, telling manifestly spiritually dead souls of their need for salvation, most of whom were Catholics.
For me something profound had occurred, and even nature seemed new to me (though i was now keenly aware of my sinful nature and effects as never before) and (Scripture had become alive, and i sought fellowship of the Spirit in Catholicism, but very rare was the person that I could connect with. RC charismatic groups were better, but they were hobbled by the hierarchy who try to fold them in with the nun's marxist "peace and justice commission." I also went on a couple 8 day directed retreats for my vacation, as i sought to seek the Lord more.
But I was trying to follow the Lord, and working about 60 hours a week as a truck driver/delivery man for a dairy gave me much time to hear various evangelical preachers who overall ministered life to me. I knew there were discrepancies btwn Scripture and Rome, but i did not know of any other church nearby that i felt i could jump into. So it was only after sincerely asking God "if it be Thy will to go to another church, I trust You will show me" - which He quickly manifestly did - that I left Rome for evangelicalism.
And as such I have no personal grudge against Catholicism, but due to my background and it being the predominate faith in my area then it remained a main focus, in the interest of souls, and Truth, though i contend against other faith as well .
And since that time I have learned more about the details of Catholicism (and can appreciate some things, such as the level of maturity of her scholarship, even if in error) as well as seeing the contrast btwn Catholicism, esp. the Roman version , and the NT church of Scripture.
Which disallows her as uniquely being the one true church, as well as even being a true church, though she has always retained enough Truth so that poor and contrite souls could lay on hold of the risen Lord Jesus for salvation, and thus the spiritual body of Christ, the only one true church, could continue to prevail against the gates of Hell, though paradoxically Rome has become as those gates for multitudes, as have liberal Prot. churches.
